I(18M) found gay porn on my partners(18M) phone. I don't want to leave him but I might.

So I have been with my partner for over a year and a half. We found each others personal Instagram accounts and started talking. It was a long long wait but we finally met and have been together ever since. We live about 3 hours from each other so we don't get to see each other often but when we do it's amazing. He's very sweet and supportive of me and my life.<br><br>The other day I was over at his house and I was using his computer. I was getting ready to leave and he asked me to delete my search history but I forgot to do so. So when I got home me mum asked me why I had been searching for gay porn. I lied to her and said I was just curious but I couldn't get the thought out of my head. I talked to my bf about it and he was really open and honest about it. He told me he was pansexual but I didn't really care for any of that.<br><br>However he didn't tell me the whole truth. He told me he hadn't watched porn in months. But obviously that was a lie.<br><br>I'm not sure if I can forgive him for this. I feel like he lied to me about something big. I feel like it betrays my trust in him. I'm not sure if I can move past this and I don't really know how to approach this topic. I feel lost.
